The TDR500/3 is a hand held, compact Time Domain Reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1 m and a 5 km maximum range depending on velocity factor selected and cable type.
Four output impedances are available (25, 50, 75, and 100 Ω) and a velocity factor between 0.2 and 0.99 will meet any cable test requirements.
The Teleflex VX presents the latest development of the Teleflex series. Like all Teleflex reflectometers, the Teleflex VX is specially designed to capture the fast processes during the fault location in power cables. It presents the consequent continuation of the Linux based Teleflex MX
The operation is reduced to the essential steps, and runs mostly automatically. The completely new hardware of the Teleflex VX with significantly improved parameters, as for example sampling frequency, pulse width and pulse amplitude results in ranges of up to 1000 km, but also in highest resolution in the close range.
Measuring hardware and display are separated, and communicate via Ethernet. This allows the easy integration into a fault location system and allows the operation in offshore application, for example, the remote operation in ROV’s.
The Teleflex LV Monitor is for the location of faults on low voltage cables, especially for the detection if intermittent fault, which result in specific difficulties. Additionally the voltage and current waveforms are recorded.
The stored data is retrieved from a PC or Notebook via Bluetooth or via a telephone connection (Line or GSM).
In opposition to other portable reflectometers, the Teleflex LV monitor is permanent and simultaneous connected to all three phases of the LV cables and permits the user to do a reflection measurement on all the phases and their combinations, either locally or in remote operation. The supply of the Teleflex LV Monitor happens by one of the connected phases.
